L-(+)-(2R,3R)-, D-(−)-(2S,3S)- and meso-(2R,3S)-tartaric acid as Fischer projections and skeletal structures, with the mirror plane of the meso acid and their properties. ## What the template shows - The compound Pasteur resolved by hand in 1848: two enantiomers and an optically inactive meso acid - 2,3-Dihydroxybutanedioic acid - L-(+)-tartaric acid - natural, dextrorotatory - D-(−)-tartaric acid - mirror plane - meso-tartaric acid - achiral, optically inactive - Natural (grape) tartaric acid is L-(+)-(2R,3R); its enantiomer D-(−)-(2S,3S) has the same melting point and the opposite rotation, [α]D about ±12. - meso-Tartaric acid (2R,3S) has a mirror plane: it is achiral and optically inactive, and its melting point and solubility differ from the enantiomers. - Racemic tartaric acid (DL, "racemic acid") is a 1 : 1 mixture of the enantiomers and crystallises differently (mp about 206 °C). - Pasteur separated the mirror-image crystals of sodium ammonium tartrate with tweezers: the first resolution of a racemate. - Wedge = toward you, hash = away from you · every part of this figure is editable Drawn with 30 atoms, 25 shapes – every one editable in MolDraw. ## Sources - [Clayden, Greeves & Warren, Organic Chemistry, 2nd ed., OUP 2012, ch. 14](https://openlibrary.org/isbn/9780199270293) Textbook - [Eliel & Wilen, Stereochemistry of Organic Compounds, Wiley 1994, ch. 7](https://openlibrary.org/isbn/9780471016700) Textbook ## How to use this template 1. Press **Edit in MolDraw**. The template opens on the canvas of the free MolDraw editor. 2. Change anything: move structures, edit atoms and labels, recolour highlights or delete what you do not need. 3. Add your own structures, arrows and text next to it, or combine several templates on one page. 4. Export the drawing as PNG, SVG or PDF for slides, worksheets, theses and papers. ## Frequently asked questions ### Is the Tartaric acid stereoisomers template free? You can preview the Tartaric acid stereoisomers template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates. ### Can I edit the Tartaric acid stereoisomers template? Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it. ### Is the chemistry checked? Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page. ### Are the R/S labels in the stereochemistry templates checked? Yes. Every R/S and E/Z descriptor is computed with RDKit from the drawn structure, so the labels match the wedges and dashes. ## More stereochemistry templates [**Assigning R and S**Free · Stereochemistry](https://www.moldraw.com/templates/stereo-rs-assignment/)[**Newman projections: butane**Free · Stereochemistry](https://www.moldraw.com/templates/stereo-newman-butane/)[**Cyclohexane chair and ring flip**Free · Stereochemistry](https://www.moldraw.com/templates/stereo-chair-ring-flip/)[**CIP priority rules**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-cip-rules/)[**E/Z and cis/trans alkenes**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-ez-alkenes/)[**Enantiomers and diastereomers**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-enantiomers-diastereomers/)[**Meso compounds: 2,3-dibromobutane**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-meso-dibromobutane/)[**Fischer projections and D/L**Premium · Stereochemistry](https://www.moldraw.com/templates/stereo-fischer-dl/) ## Related pages [**Chirality & R/S Configuration Worksheet**Free printable worksheet](https://www.moldraw.com/educational-materials/chirality-rs-worksheet/)[**Structural Isomers & Stereoisomers Worksheet**Free printable worksheet](https://www.moldraw.com/educational-materials/isomers-worksheet/)[**All Stereochemistry templates**17 templates](https://www.moldraw.com/templates/stereochemistry/)[**All chemistry templates**370 templates in 29 categories](https://www.moldraw.com/templates/) MolDraw Pro Download all 370 templates - Export the 291 premium templates as PNG, SVG or PDF - AI chemistry assistant - Structure scanning from images - Cloud save and teaching slides [See Pro plans](https://www.moldraw.com/pricing) Free templates stay free.
